My six year old Electolux Dishlex DX 403 dishwasher stopped heating the water.I found comments on the internet about burnt out solder joints in the control box.A friend opened the control box and found a blackened area on the back of the circuit board.Once the connection was re-soldered the water heated again.We also found that quite a few wires leading to the control box had overheated and the insulation had melted.Considering that this dishwasher was the top model from Electrolux at the time, I was not impressed.I had previously had a Vulcan Dishlex for almost 20 years.
Thanks to those people who previously posted information about this fault.

mine had this exact same problem - it turns out that the relay on the control board had not been soldered on properly. mine has shorted out over time, and caused a lot of charing of the localised area. i checked the relay, it was okay, so have resoldered the board and all is working for now.

i called Electrolux - 1800 001 218 - to report the problem, as i believe there are too many peoplew reporting this issue for it to be a one off. i was also concerned about a fire risk, as the charing on mine was considerable.

too be blunt, Electrolux didn't seem to care too much, unless if i wanted to pay to have someone come look at it, despite the fact that i am an electrician.

Electrolux currently say that this is the first time this problem has been reported - despite that fact they are aware of this thread. i would encourage anyone whoi has this fault to call the above number and report your problems to them, as i believe a recall may be waranted, and, should your unit have serious problems (fire) it is on record.

Electrolux currently have a recall on a couple of other dishwashers due to the fact they pose potential fire risks - see www.recalls.gov.au

If the dishwasher is hanging on in the middle of the cycle it is usually the heating system. If the temperature of the water is going up after filling, then the element may be working. The element is tested using a multi meter set on Ohms to read impedance across the heater element contacts. If impedance is infinity (open-off limit), then the element is gone. If the element is OK, then the bi-metal thermostat or the fuse must be replaced. The heating assembly is located at the base of the appliance, behind the kick panel.

Behind the kick panel you should also find the tech sheet illustrating how to run the diagnostic cycle for this model. Run a diagnostic cycle to confirm that the problem is with the heating system. Drain, water sensor and inlet problems sometimes may also result in cycle not finishing.

If your dishwasher is not heating properly, troubleshoot the issue. You can often repair this problem and eliminate service fees.

Incoming Water Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.

Thermostat The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.

Heating Element/Drying Fan

The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.

Additional Concerns

If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon dishes don't usually completely dry. You must towel-dry these items.

Found I had no hot water in my Dishlex DX302 and did a google search and
found this page.

My problem was found to be the same as the others; one of the solder
joints on the relay on the control board had arced off.
You could see the burn mark on the board and cover where it had been
arcing.

Soldered it back together, and now it seems to be going good again.
Now my only problem is a damaged door seal, which means a small water
leak; I have used part of a rubber glove to bridge the gap, and it
reduces the water leak.
